'Clean' in the Bible

Elisha sent a messenger to him, saying, “Go and wash in the Jordan seven times, and your flesh will be restored to you and you will be clean.”

Are not Abanah and Pharpar, the rivers of Damascus, better than all the waters of Israel? Could I not wash in them and be clean?” So he turned and went away in a rage.

Then his servants came near and spoke to him and said, “My father, had the prophet told you to do some great thing, would you not have done it? How much more then, when he says to you, ‘Wash, and be clean’?”

So he went down and dipped himself seven times in the Jordan, according to the word of the man of God; and his flesh was restored like the flesh of a little child and he was clean.
